Another thing - when we brought Max home, Jake surprised us by working very hard to be Alpha. We were shocked, because he never seemed very dominant. Jake was constantly humping Max. Max put up with it for many days before he finally just snapped and bit Jake. That was a big vet bill, and we were grateful not to have lost Jake. His whole head fit in Max's mouth, and I'm sure Max could have done much more damage than he did.

So - be careful with the introductions and don't assume your sweet, gentle girls will stay that way while they're establishing their pecking order.
